Things I liked: Powerful, accurate, and fairly light, easy to fill, load, and shoot.
Doesn't seem too picky when it comes to pellets/accuracy..

Things I would have changed: Automatic safety would be nice.
Tighter fit for the pellets in the loading port/breach part of the barrel, pellets tend to fall into the brass bushing when holding the rifle upwards.. If you fire the gun with the pellet in the brass bushing, the pellet will jam in the breach.
